How much I care for soccer is infinetessimal. When I was very young I played on a soccer team. Our practices were pointless and the only person with any ability was the coaches infaturated son. As a result, that season I scored an infinitessimal number of goals and the team won an infinitessimal number of games. Because of this, I have an infinitessimal interest in soccer.
